Hi, just a followup message.
I'm now running the buildworld mentioned above, and the system is pretty
much unusable. It exhibits the same symptoms as I have mentioned before,
mouse jumpiness, bogus mouse input (movement, clicks), and the system is
generally very jerky and unresponsive. This is particularily evident
when doing things like webpage loading/browsing/rendering, but it's
noticeable all the time, no matter what I am doing. As an example, the
last sentence I wote without seeing a single character on screen before
I was finsihed writing it, and it appeared with a lot more typos than I
usually make ;)
I'm running *without* invariants and witness right now, i.e. a kernel
100% equal to the SCHED_4BSD kernel.
Best regards,
